生物的性别一般是由遗传基础所决定的,性别不同,其生理生化、新陈代谢反应等也应该会有所不同。为了探索中华猕猴桃雌雄株间的差异,我们做了叶片糖分含量测定,发现雌株和雄株可溶性糖含量有着明显的差异。 5月上旬,分别在已开花的雌株和雄株的同一部位上,各摘取5—7片叶子,去掉叶柄,在80℃恒温箱中烘干至恒重,研成粉末,过 Biological sex is generally determined by the genetic basis, gender, its physiological and biochemical, metabolic reactions, etc. should also be different. In order to explore the differences between male and female plants of Actinidia chinensis, we made the determination of the sugar content in the leaves and found that the soluble sugar content of the female and male plants were obviously different. In early May, respectively, in the same parts of the female and male plants have been blooming, respectively, pick 5-7 leaves, remove the petiole, 80 ℃ oven dried to constant weight, into a powder,
